SPECIFICATION.

To all whom it may concern:

Be it known that I, Honnrro N. WArnns, otMeriden, in the county of NewHaven and State of Connecticut, have invented certain new and usefulImprovements in Feed-Water Heaters for Steam-Generators; and I do herebydeclare that the following is a full, clear, and exact descriptionthereof, whereby a person skilled in the art can make and use the same,reference being had to the accompanying drawing and to the letters ofreference marked thereon.

l My present invention is an improvement upon the invention for whichLetters Patent of the United States were issued to me on the 18th day ofFebruary, 1868. It consists in a new arrangement of the entrance-steampipe and sprinkler within the reservoir, whereby a deflector over theend of the said pipe is dispensed with, and the steam still brought intoimmediate contact with the spray of water from the sprinkler, and heldthere a sufficient length of time to heat the water to the boiling pointand separate the impurities.

In the accompanying drawing, A is a section of a cylindrical reservoir.B is the entrancepipe for the exhaust steam from the cylinder of theengine to pass into the heater. C is asprinkler pipe, pierced with smallholes, through which the cold water enters the reservoir in finejets. Dis the cold-water pipe, leading to the sprinkler either from a pump oran elevated tank. E is the exit-pipe, for the waste steam to pass offinto the atmosphere. I is the pipe by which the hot water is drawn offto feed the boiler. J is a device for retaining the water in thereservoir so that it shall not fall below the level of the interior ofI, and is fully described in my previous patent before mentioned. K is ahandhole, for cleaning out the interior of the heater and removing thesediment that falls to the bottom of the reservoir.

The steam-entrance pipe B passes into the reservoir through the bottom,and curves over, as shown in the drawing, to permit the sprinklerpipe Cto be placed within it, or partially within it, as shown. My inventionis intended to be placed in the upright portion of the exhaustpipe of asteam-engine.

The steam enters through the pipe B and strikes the water issuing fromthe holes in C, dashing it into fine spray, and heating it at once tothe boiling point. The impurities in solution and suspension in thewater are separated, and fall to the bottom of the reservoir with theheated water, which fills the reservoir, if not drawn down by the pump,up to the level m of the overflow. The force of the blast of the steamdashes some of the water in the form of spray against the side of thereservoir, but not upward, in the direction of the pipe E, so that itcan be blown out by the force of the waste steam as it passes out fromthe heater.

By means of my present invention the deflector over the mouth of thepipe E, for the prevention of the water being blown through theexit-pipe, can be dispensed with.

Claims.

What I claim as my invention is- 1. The curvedentrance-pipe B, when usedin the interior of a feed-water heater-chamber to project the steamdownward 0r laterally against a sprinkler-pipe, substantially in themanner described. a

2. The arrangement of the cold-water sprinkler pipe within thesteam-pipe, and the steampipe within the hot-waterreservoir,substantially in the manner herein described.
